To all whom it 'may concern;

Be it known that I, HOWARD STLLMAN, of Berkeley, in the county o iAlameda and State orn California., have invented a certain new anduseful Improvement in Car- Brakes, of which improvement the following isa specification. l

My invention relates xto means for manually effecting the applicatioiiofbrakes on railroad cars, and its object is fto.provide an appliancewhereby the brakes f a car may be set from the outside of the cfa'r,while the ear is in motion, by a. brakem'aijivrid'ing on the side sillstep, and the brakes` be quickly and positively applied from"theiouts-ide o the car, without interference Withqthe means in theinside of the car for manually applying the brakes or with' the airbralt'esystem, and. without requiring the brakeinan to go inside thecar.

The improvement claimed is hereinafter fully set forth. ff

l'n the accompanying drawings: l `ignre 1 is a view, in elevation, ofthe blind end-"of a mail or baggage car, illustrating an application ofmy invention; F ig. 2, a horizontal section through the same; Fig. 3, aljigi tudinal central section, on an enlarged scale,

through the supports of the ratchet mecha-i nism, with the latter inelevation; and,

4, a front view of theratchet-mechanism;l

My invention is herein exemplified in conf' nectlon with the ordinarymeans of manifixed to the car end, and therebytl-I projecting throughthe end of the car, 'and being connected to a. brake chai-11,17, which,in-its rotation, is wound upon it, and which gasses around sheaves, 8and 9, tofV the ,brake 'gging in the same manner as-lthe brake chain ofthe usual hand Wheel. An operat ing ratchet, 6, and a locking ratchet,6F, are fined upon the. shaft, 6, the" operating ratchet, 6, beinglocated on the oiitsd of the car and adjacent to the endv ofA th' shaft-6. A ratchet lever, 10, journal'ed-ojnQ-the outer end of the shaft, 6,carries antolieratf I ing pawl, 10, which oscillates upon-a piv'lt onthe ratchet lever and isnornia1ly,'.:,eii gaged with the teeth of theratchet, (je, by a spring, 10". A lateral releasingdog or projection,10c, formed on thepawl, 10?, is adapted to abut against a stop,11,-i2ied to the car end, when the ratchet lever iS'fiiiiflvedl into theposition shown in Fig. l, in which position it abuts against alever'fstog,i 12, 1.5m"

gage the pawl from the teeth of theopi'atf ing ratchet, 6". i A pawlshaft, 13, journaled in bearings, 13, below the brake chain shaft,carries' a locking pawl, 13", which is adapted t gage the lockingratchet, 6b, ofthe chain shaft, 6, and thereby to preven rotation of thelatter in direction opp e to that imparted by the movement/o -thge uallyapplying brakes in the inside of a carl bogly, 1,-at the blind ornon-vestibuled end: thereof, the saine-consisting of a hand Wheel, 2,indicated in dotted lilies in Fig. l, having.A its shaft, which isjournaled on a suitable; member of the car frame, connected to a' brakechain, 3, which is Wound on the shaft by the rotation` of the handwheel, andff vpasses therefrom, around sheaves, 4. and 5, to the brakerigging, which may be of anyV 4 of the well known forms, and, as it doesnot,

ont invention, is not shown.

In order to enable the brakes to be alp-.i plied, when required, fromthe outside of,

handle, 13, which is weighted on itsfotefend, by the movement of which,the 'pawlf,

13b, may be released `from the lookin? -i'ra tchet, 6b, and a curvedarm, 13,, projet; zing in opposite direction to the handle, 13,` 'ftheouter end of said arm being so located' asto be contacted with, andmovedthe '.'iatchet lever, l0, when the latter'isbroughti, ,-"upito ornear the stop, 12, and thereby-,to

rok the pawl shaft, 13, about its axis anfd1 t Ifrelease the lockingpawlfrom the ratchet,6"gI in andof itself, :form any part of my pres In.applying the brakes, the brakeman,

iles

ratchet lever, l0, with his right hand, the

movements ot said leier inthe direction of the arrow, Fig. l, winding upthe chain, 7,

on the shaft, 6, and said shaft being held stationary, in the oppositemovements of the lever, 10, by the locking pawl and' ratchet, 13'J and6". lthe ratchet lever are sufficient to set the brakes, after'which, ifthe ratchet lever lbe left in or near a vertical position, the brakes Afew movements oli lio will remain applied, the brake chain shaft, G,continuing to be held stationary by the locking pawl and.` ratchet. Thebra-kes may be released, whenever desired, either by 5 moving theoperating handle, 13, so as to disengage the pawlfsf from'tne ratchet,Gb, or by moving the ratchet lever, 10, into contact with the stop, l2,in which position both the pavvls, a and 13b, will be disengaged fromtheir respective ratchets.

it will be noted that the appliance above described and the usual insidehand brake wheel are independently operable, and have no relation one tothe other, and that either may be used for applying the brakes Withoutinterference by the presence of the other; also 'that the brakes may beapplied and released by iiuid pressure mechanism in the ordinary manner,and thatI the requirements 2o of the interstate Commerce Commission, asto the provision of means for applying the brakes by hand While thc caris in motion, are fully complied with by the use of my improvement.

l claim as my invention, and desire to secure by Letters Patent:

l. rlhe combination, with a railroad car, of means for manually applyingthebrakes, operable from the inside of the car, means $0-, forn'ianually applying the brakes, operable from a side sill step of thecar, means for releasing the brakes, also operable from said step, andmea-.is for actuating said releasing means by the movement of theapplying means to a determined position.

r1`he combination, with a railroad car having a blind or non-vestibuledend, of a brake chain shaftjournaled horizontally on and project-ingthrough the blind end of the body, a brake cham extending therefromtov-a connection with the bra-ke rigging of v thecar, an operatingratchet and a locking ratchet fixed onl the brake chain shaft, a ratchetlever journaled on 'said shaft adjoining the outside of the car body,and operable, in a vertical plane, from a side step A of' the car, apawl coupled to said leyer and adapted to engage the operating ratchet,a pawl adapted to engage the locking ratchet,

a lever stop fixed to the outside of t-he car body, and means fordisengaging said pawls from their respective ratchets, to effect therelease of the brake, when and Whenever the ratchet lever is moved intocontact With the lever stop, whereby such position of the ratchet lever-is always an indication to a brakeman that the brake is released.

3. The combination, with a railroad car, of a brake chain shaftjournaled on the car l body, a brake chain extending therefrom to aconnection with the brake rigging of the car, an operating ratchet and aVlocking ratchet, each fixed on the brake chain shaft,

a ratchet lever journaled on the'brake chai v shaft outside the` earbody, a pawl coupled to said lever and adapted to engage the operatingratchet, a pawl shaft journaled adjacent to the brake chain shaft, :apawl on said shaft adapted to engage the locking ratchetof the brakechain shaft, and an operating handle ,fixed on said pawl shaft outsidethe car body for engaging and disengaging the pawl thereof and thelocking ratchet.

4. The combination, with a railroad car, of a brake chain shaftjournaled on the car body., a brake chain extending therefrom to aconnection with the brake rigging of the car, an operating ratchet and alocking i ratchet, each fixed on the brake chain shaft, a ratchet leverjournaled on said shaft outside the car body, a pawl coupled to saidlever and adapted to engage the operating ratchet,

a pawl shaft journaled adjacent. to the brake chain shaft, a pawl onsaid pawl shaft adapted to engage the locking ratchet of the brake chainshaft, and an arm fixed on said pawl shaft in position to contact withthe ratchet lever atone extremity of the traverse thereof.
